Electronista, which got wind of the announcement, reports that the LG Optimus EX will not only replace the LG Optimus 2X but will also pack more powerful specs than the latter–especially with the Optimus EX’s 1.2-GHz dual-core NVIDIA Tegra 2 processor.

LG Mobile has not revealed plans of bringing the LG Optimus EX beyond South Korea, although it is possible for the Android smartphone to reach the U.S. through T-Mobile, which has been the only carrier to release the LG Optimus 2X.

The LG Optimus EX reportedly has a 4-inch WVGA (800×480) IPS display with a brightness of 700 nits, making the screen render vivid colors even under direct sunlight. It runs Android 2.3 Gingerbread.

The Android smartphone also supports HD video output and 1080p video recording. The LG Optimus 2X was only capable of up to 720p playback and recording. The LG Optimus EX also supports Wi-Fi, Bluetooth, HDMI, and DLNA.
